Multiple Choice quiz using php [duplicate]

This question already has an answer here:

• Getting checkbox values on submit 7 answers

I am trying to create a quiz using php. The idea of the quiz is that the using is given a question like "what sport do you already play?" with a number of different checkboxes allowing them to chose what sport they have played. When the users clicks the submit button the system will display a sport based on what checkboxes the user has clicked, for example if they chose football and rugby they could be given the answer basketball.

All the example that I have found online only should a quiz that allows the user to pick on answer online. How would i create the system using php to allow the user to chose any number of answers?

Here is my form

<form>

<p>What Sport Have You Played Before?</p>
  <input type="checkbox" name="sport" value="football">Football<br>
  <input type="checkbox" name="sport" value="rugby"> Rugby<br>
  <input type="checkbox" name="sport" value="basketball"> Basketball
   <input type="submit" name="Submit"/>
</form>
